rAn'rIrIonsrnIr ron comrosrrron 'rnoonme Application filed January 31, 1929. Seria1'1q'oa336fl 87.

This invention relates "to partition ,strips for composition flooring, such as terrazzo and the like, and aims to provide a strip that is formed with positivemeans for anchoring in the hard cement disposed in said pockets so as to absolutely prevent'the strip from moving in any direction. Furtherniore, the

angle of the wings is such as to create equal pressure receiving surfaces at opposite sides of the strip resulting in a positive anchoring of the strip within the cement. I

An additionalobject, is to provide anchorage means that will absolutely not necessitate the forcinggofthe anchor entirely into the cement bed. The structure is such that even though the lower portion onlyof the various anchors is forced into the cement, a positive anchor will be had until the terrazzo is laid.

A further and additional object is to pro vide a partition strip of this character, wherein the anchorage means is an integral part thereof,-an'd that can be struck from the strip by not more than two mechanical operations, with the result that the complete strip can be manufactured at nominal cost;

With the foregoingand other objects in view as the nature of. the invention will be better understood from the following specification in accompaniment with the drawing, wherein like reference characters indicate cor- I views, and wherem: 1

formed at a throughout the length of the strip, and are Figure 3 is'a fragmentary side elevation of the improved strip, and

as well as being of any. The various anchors are predetermined spaced points suitable design.

alternately at opposite sides of the strip as in F iguresl, 3 and 4, Furthermore, these anchors are beneath the center line of the strip, and in each instance, they are produced by spaced pairs of relatively wide ,V-shaped lncisions 6-6, the apices of. which are di-l rectly opposed to each other, and are parallel with the longitudinal axis of the strip, see Figure 3. The upper ends of these incisions are slightly beneath the center line of the strip, while the lower ends thereof are likewise spaced from the lower edge of'the strip. After, making 'the incisions in the strip, the material betwen the complemental ones of the pairs is forced directly outwardly to provide opposed relatively wide V-shaped wings 7- 7. The formation of these wings will also provide similarly shaped slots 88 in the strip, so as to permit the cement to pass therethrough when the lower edge of the strip is embedded in the cement A, as in Figure 2. Tue opposed wings 7- -7 will cooperate with 35 the strip 5 for providing a pocket 9 within the confines of the opposed wings for the reception of the .cement as also disclosed in Figure 2. The ends of the wings as well as the app esof the slots will be firmly bound to the ce ent to prevent movement of the strip therein. The inclined faces and edges of the wings will also be encounteredby the cement as to provide further means to prevent slippage of the strip. Even though the lower half ofthe strip is not. entirely embedded in the cement, as shown in Figure 2, a suflicient amount of the cement will pass through the slots and into the pockets as well as encounter the angled wings to prevent movement of the strip.

ing connected at their opposite ends to the In view of the foregoing description when considered in conjunction with the accompanying drawingflt will be apparent to those skilled in the art, that I have provided a novel, simple and useful partition strip for I composition flooring, that is well adapted for all of the purposes designated, and even though I have herein shown and described the strip as being composed of anchors constructed in a particular manner, and of a particular shape, it is of course to be understood that I do not desire to be so limited, as certain changes may be made without departing from the spirit and scope of the appende claims. I

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a partition strip for composition flooring, pairs of substantially -V-shaped ogposed wings struckfrom the strip to provi e cement receiving pockets in the strip as well as slots through which the cement will pass when the strip is forced into the composi-.

tion flooring plastic material base, said wings being formed beneath the center line of the strip and having their apices in close spaced relation.

2. In a partition strip for composition flooring, pairs of substantially V-shaped opposed wings struck from the strip to provi e cement receiving pockets in the strip as well as slots through which the cement will pass when the strip is forced into the composition 7 flooring plastic material base, said wings being formed beneathfthe center line of the strip and having their apices in close spaced relation, and in a plane parallel with the longitudinal axis of the stri 3. In a partitions strip ibr composition flooring, a plurality of substantially V-shaped wings struck fromthe strip at spaced points throughout the length thereof, said wings bestrip and forming when struck from the strip a plurality of cement passage slots within the strip. f

In testimony whereof I aflix my si ature.
